Terra Prime expansion

I've been considering what I'd want to put into a Terra Prime expansion for some time, and today I spent some time putting together a prototype of the expansion. Here's what it includes:

2 new Upgrades: a Matter Converter which makes your resource cubes interchangeable, and Additional Module Slots ("Extra Deck"?) which gives you 2 new slots for modules - one Engine/Cargo slot and one Weapon/Shield slot.

3 new Modules: a Pulse Cannon, which lets you roll 2 dice, but costs 1 energy to use; a Cryo-Chamber, which lets you carry a Colony marker but no cubes (upgrades to a standard 2-door module); and an Afterburner, which I've got two possible rules for...
1. 2 actions at the cost of 1 Energy, once per turn
2. 2 actions per turn, but only one non-move action can be taken that turn

27 Exploration tiles: The setup for the expansion is to place the Space hexes face up, and these Exploration tiles are placed face down in the center of each in lieu of what's printed on the tile. In addition to Hostile Aliens and Stray Asteroids, I added a couple new features...
* Sunstar: makes planets on the tile uninhabitable. Thus you cannot place a colony on a planet or asteroid on a tile with a Sunstar. I'm considering making that "cannot place a colony in any sector adjacent to the Sunstar."
* Wormhole: there are several Wormhole tiles. With 1 move action a player can move their command ship into an adjacent wormhole, and with 1 more move action a player can move from the wormhole to any sector adjacent to any wormhole tile on the board.

3 additional Reward tiles: I haven't made any new ones, for now I just grabbed 3 reward tiles from another copy of the game. I'm doubling up on the Greenium/Energy, te Bluium/Energy and the Yellium tiles from phase 3. Instead of the Yellium tile I think I'd rather add a Brown+Energy tile to Phase 2.

Now that I've made the prototype I'd really like to try it out!
